(I) Background. Conflicts emerge when populations of protected species grow to sizes that cause noticeable economic damage - like in the case of the fish consuming Great Cormorant (Phalacrocorax carbo sinensis). One possible approach for reconciliation is to regulate the size of the population in question. In doing so, regulation strategies have to meet multiple targets: 1) population size has to be reduced; 2) the viability of the population has to be maintained; 3) strategies have to adhere to the available budget. This thesis focuses on the regulation of populations that are structured into two groups - breeders and mature non-breeders. The pool of non-breeders provides a reserve for the breeders, whereby they may enable the population to resist regulation attempts. (II) Aims. 1) Development of a modeling framework and a conceptual model to provide an understanding of the functioning and effect of the population structure induced by non-breeders on population dynamics in a fluctuating environment. 2) Uncover the relation between non-breeder characteristics and the performance of regulation strategies. 3) Application of the modeling approach to the regulation of the Cormorant in order to evaluate the results from the conceptual model and find statements to support decisions on management strategies. (III) Methods. A conceptual stochastic time-discrete model, based on the logistic map with overlapping generations, is developed. Different types of threshold regulation strategies are applied. Strategies differed in which part of the model was affected by regulation. Resulting rules from the conceptual model are tested by applying them to a second age-structured model of a cormorant population, parametrized with data gained from a cormorant colony in Denmark. Analyzes of this model focus on the ecological-economic performance of regulation strategies and result in rankings of regulation options. Regulation performance is judged from different economic perspectives.

Exploring age structure in Mediterranean cultures illuminates the social dynamics of intergenerational relationships that became more visible in late first and early second century early Christian texts, and especially in 1 Timothy 5. This was a time of crisis when those with a living memory of the foundations of the movement were almost gone, and the community was scrutinized by outsiders. Since we have relatively few clues related to aging and age structure in the extant texts, a model of generational stability and social change based on ethnographic data helps us to imagine culturally sensitive possibilities that we can then test out as we reread the texts in their Roman cultural context. In his fictive story of Paul and Timothy, the author of the heterographical (pseudepigraphical) letter of 1 Timothy establishes an ideal intergenerational relationship between “Paul” as an older man and “Timothy” as his adult “child.” When the fictive Paul directs Timothy to speak kindly to older people (5:1-2), he introduces a section on age-related issues. Behaviour that was causing concern for public reputation included adult children shirking filial duty (5:4, 8), young widows gadding about in public (5:11-15), and younger men accusing their elders (5:19). These behaviours threatened the reputation and honour of the community and may have been encouraged by the opposing faction. The author’s solution was to reject the opposing teachings and enforce behaviour that reflected proper age structure: adult children should fulfill their filial responsibilities and care for widowed mothers and grandmothers (5:4); young widows should be guided and supported by middle-aged women who were responsible for them in the age hierarchy among women (5:16); middle-aged women should imitate the exemplary behaviour of the enlisted widows who were over 60 years old; and young men were to be rebuked in front of everyone for their disrespect toward elders (5:20). In the face of social change, the author advocates for behaviour reflective of the traditional age structure of Roman society.

Japan står inför en stor utmaning; en snabbt växande åldrande befolkning i kombination med en minskad arbetsför befolkning. Denna uppsats syftar till att försöka förklara vilka effekter landets åldrande befolkning får för landets ekonomiska tillväxt, samt vilka faktorer som kan dämpa dessa effekter. Analysen görs med hjälp av en modifierad version av Solows tillväxtmodell som teoretisk bas. Detta görs för att skapa en förståelse för vilka faktorer som påverkar ett lands ekonomiska tillväxt. Med hjälp av denna modell tas befolkningens åldersstruktur med som en parameter. Den utvecklade modellen ligger sedan till grund för en empirisk analys av hur Japans ekonomiska tillväxt kan komma att påverkas som ett resultat av landets åldrande befolkning. Resultaten visar att Japan kommer att drabbas av sjunkande tillväxt på grund av den åldrande befolkningen. Likväl finns det möjliga lösningar till hands för att dämpa de negativa effekterna, exempelvis en ökad sysselsättningsgrad hos kvinnor, ökat humankapital, ökad invandring samt en kostnadseffektiv teknologisk utveckling. / Japan will face a major challenge with regard to its rapidly growing aging population combined with a reduction in its working population. This paper aims to explain the impact of Japan's aging population and the country's economic growth, and the factors that may mitigate these effects. The analysis is done using a modified Solow growth model as a theoretical base. This is done to get a more in-depth understanding of the factors that affect a country's economic growth. By using this model, that includes population age structure as a parameter, we have the basis for the empirical analysis of how Japan's growth may be affected as a result of the aging population. The results show that Japan will suffer from declining growth due to its aging population. However, there are possible solutions to mitigate the negative effects, such as increasing employment rates among women, increased human capital, increased immigration and a cost effective technology development.

<p>The population of Sweden is ageing as in almost every European country. Improved medical progresses and treatment options lead to a decreasing mortality at older ages, increasing life expectance and an advanced health of the elderly. Due to these improvements and the so called ‘baby- boomers’, a great number of persons born in the 1940s that will reach retirement age the coming years, their total number will increase strongly in the near future all over Sweden. To enable these elderly to live a normal, active and independent life as long as possible activities, services and special housing with improved accessibility and meeting places for elderly has to be provided. Thus, for local authorities it is essential to know the actual and favoured living conditions as well as environments of elderly. This study aims therefore to investigate the characteristic of preferred residential neighbourhoods of the elderly in the city of Norrköping. The demographic, social and crime situation was examined for the districts of the city using several methods from both Statistics and GIS. Statistical methods included classifications, indexes or indicators and bivariate correlations. A model was developed to combine demographic and social data to characterise districts. GIS was to a major extent used as a visualisation tool. Choropleth mapping and Kernel density estimations were used to illustrate distribution of elderly and crime. Preliminary global statistical tests were used to verify clustering in the crime data set. An accessibility analysis was conducted with the help of the network analyst tool. Results indicate that districts experiencing the highest total numbers and proportion of elderly are very distributed throughout the city of Norrköping. They are, with some exceptions, characterised by lower social status. Four districts of the city show considerable evidences of demographic ageing, experiencing a population pyramid formed like an urn. Beside districts where elderly constitute a bigger proportion of the population, they tend to live in districts characterised by a relatively high proportion of young adults aged between 20 and 29. Crime analyses have shown crime clusters in different parts of the city. A high proportion of elderly faces a high crime level in the districts Gamla staden, Nordantill and Hageby. However, it has been proved that only some hot spots of crime within these areas contribute to the high crime level. Districts such as Skarphagen, Såpkullen, Smedby and Linö, all (except Såpkullen) situated on the outskirts of the city, hold high or middle elderly and a low crime level. Accessibility analyses have shown that elderly aged over 80 do not live significant closer to health centres and the public transport stops compared to the age groups 20 – 65 and inhabitants aged between 65 and 79.</p>

Management strategies to prevent overfishing while achieving optimum yield vary according to the available data and life history of the fished stock. I evaluated two sets of management strategies for Pacific coast rockfish: strategies to set harvest limits for data-poor stocks, and strategies intended to protect the age structure of fished stocks. Setting Harvest Limits for Data-poor Stocks - The collapse of canary rockfish, Sebastes pinniger, in the northeast Pacific began more than two decades before the stock was officially declared overfished. The 2006 reauthorization of the Magnuson-Stevens Fishery Conservation and Management Act requires a scientifically-based harvest limit for all fished stocks, including those with data limited to catch. Two such "data-poor" methods are currently in use for the management of west coast stocks, depletion-corrected average catch (DCAC) and depletion-based stock reduction analysis (DB-SRA). To evaluate the performance of each method when challenged with catch and biological uncertainty, I retrospectively applied the methods to the catch and biological data available at the time of the first and second canary rockfish stock assessments in 1984 and 1990. In 1980 canary rockfish would be classified as "data-poor", and in 1990 as "data-rich". To evaluate the sensitivity of DCAC and DB-SRA to error in the catch data, harvest limits were estimated using both the historic catch data from each assessment, and the reconstructed catch data from the most recent stock assessment. In addition, harvest limits were estimated using simulated catch data sets for the years 1916 to 1983 with increasing variability around the true catch. DCAC and DB-SRA estimated harvest limits were significantly lower than the catch recommended in both the data-poor and data-rich stock assessments, but higher than the "true" overfishing limit. Use of current catch data improved the estimated harvest limit when the stock was data-poor, but not when the stock was data-rich. The simple methods responded to increasing error in the catch time series with decreasing mean estimates of the harvest limit, indicating that these methods are highly precautionary for this species, when the catch time series is the only source of error. Age Structure Management Strategies - In a variable oceanographic environment, a population with many reproductive age classes benefits not only from the increased fecundity of older fish; but also, in some species, an increase in larval fitness. Older females may also spawn at different times or over longer periods than younger females, increasing the probability of larvae encountering favorable environmental conditions. Despite the accumulating evidence for the importance of age structure to long-term population viability in harvested fish populations, long-lived west coast rockfish (Genus Sebastes) are managed with a biomass-based harvest control rule. I compared three strategies for age structure management, and evaluated the strategies relative to the status quo, biomass-based harvest control rules, across three rockfish life histories. I examined the tradeoff between yield and traditional management reference points, as well as performance measures that could serve as management reference points for age structure. Yield was reduced by strategies that maintain "old growth" age structure, but annual variation in the catch and the probability of becoming overfished were also reduced. The longest-lived rockfish benefited the most from strategies that maintained older fish in the population through dome-shaped selectivity. The shorter-lived rockfish benefited from adjustments in the catch limit based on the age composition of the catch one year previous. Achieving "pretty good yield" with management strategies that also decrease the potential for overexploitation is an important goal for stocks that are well-studied and those that are poorly understood; these investigations contribute to a growing literature on alternative approaches to sustainable fisheries management. / Graduation date: 2012

Die vorliegende Arbeit untersucht am Beispiel der Stadtstaaten Berlin und Hamburg konkrete Handlungsoptionen des strategischen Personalmanagements angesichts unausgewogener Altersstrukturen in der Landesverwaltung unter den Rahmenbedingungen des öffentlichen Dienstes. Vor dem Hintergrund einer abnehmenden Erwerbsbevölkerung und der sinkenden Attraktivität des öffentlichen Dienstes als Arbeitgeber wird das Thema „Personal“ als die Schlüsselressource für die Leistungsfähigkeit der deutschen Verwaltung identifiziert. Die Untersuchung zeigt auf, wie eine absehbare Überalterung des Personalkörpers die Leistungserbringung der öffentlichen Verwaltung beeinträchtigen wird. Sie weist nach, dass sich beide Stadtstaaten bereits heute mit punktuellem Fachkräftemangel in technischen und Spezialisten-Berufen, aber auch bei Lehren und Ärzten, konfrontiert sehen. Diese Herausforderungen werden sich durch massive Altersabgänge ab dem Jahr 2015 und eine Alterung des bleibenden Personalkörpers noch erheblich verstärken. Die Untersuchungsergebnisse zeigen jedoch, dass die hamburgische Verwaltung, aufbauend auf einer langen Modernisierungshistorie und erleichtert durch Akteurszentralismus und eine ressortübergreifend abgestimmte quantitative und qualitative Personalbedarfsplanung, über einen gut institutionalisierten und gelebten Strategiekreislauf verfügt. Dies lässt den Schluss zu, dass die Hansestadt mit ihrem strategischen Personalmanagement gut für die Bewältigung der demografischen Herausforderungen aufgestellt ist. Dagegen wird beleuchtet, wie der Umgang mit dem Thema Personal in Berlin noch immer von chronischen Sparzwängen und einem Pluralismus der Akteure geprägt ist. Die daraus resultierende, hauptsächlich quantitativ agierende Personalwirtschaft und das Fehlen einer auch nur mittelfristigen Personalstrategie werfen erhebliche Bedenken bezüglich der zukünftigen Leistungsfähigkeit der Berliner Verwaltung auf. / The present study examines the potential and limits of strategic human resources management in the German civil service by analyzing the cases of the länder of Berlin and Hamburg. Against the background of a decline in the working population and the diminishing attractiveness of careers in the civil service, only a state-of-the-art human resources management can ensure the performance of the public sector in the long run. The study demonstrates how an ageing workforce is bound to lead to a reduced performance of the civil service sector. Both of the länder analyzed are already confronted with a shortage of skilled labour for technical posts, but also for teachers and doctors. These challenges are going to be further exacerbated by massive waves of retirement and a constantly ageing employee workforce in the years from 2015 forward. The study reveals, however, that the civil service of Hamburg has developed and successfully applies a progressive human resources management strategy, due in part to the city’s rather long history of civil service modernization and the relative power of its human resources planners. Hamburg therefore seems to be rather well adjusted to face the future demographic challenges. Human resources management in Berlin, on the contrary, is continually limited by the city’s chronic budget deficit and the plurality of human resources planners. The subsequent lack of a long-term human resources strategy casts considerable doubt on the future performance of Berlin’s civil service.

<p>At present, carbon sequestration in terrestrial ecosystems slows the growth rate of atmospheric CO₂ concentrations, and thereby reduces the impact of anthropogenic fossil fuel emissions on the climate system. Changes in climate and land use affect terrestrial biosphere structure and functioning at present, and will likely impact on the terrestrial carbon balance during the coming decades - potentially providing a positive feedback to the climate system due to soil carbon releases under a warmer climate. Quantifying changes, and the associated uncertainties, in regional terrestrial carbon budgets resulting from these effects is relevant for the scientific understanding of the Earth system and for long-term climate mitigation strategies.</p> <p>A model describing the relevant processes that govern the terrestrial carbon cycle is a necessary tool to project regional carbon budgets into the future. This study (1) provides an extensive evaluation of the parameter-based uncertainty in model results of a leading terrestrial biosphere model, the Lund-Potsdam-Jena Dynamic Global Vegetation Model (LPJ-DGVM), against a range of observations and under climate change, thereby complementing existing studies on other aspects of model uncertainty; (2) evaluates different hypotheses to explain the age-related decline in forest growth, both from theoretical and experimental evidence, and introduces the most promising hypothesis into the model; (3) demonstrates how forest statistics can be successfully integrated with process-based modelling to provide long-term constraints on regional-scale forest carbon budget estimates for a European forest case-study; and (4) elucidates the combined effects of land-use and climate changes on the present-day and future terrestrial carbon balance over Europe for four illustrative scenarios - implemented by four general circulation models - using a comprehensive description of different land-use types within the framework of LPJ-DGVM.</p> <p>This study presents a way to assess and reduce uncertainty in process-based terrestrial carbon estimates on a regional scale. The results of this study demonstrate that simulated present-day land-atmosphere carbon fluxes are relatively well constrained, despite considerable uncertainty in modelled net primary production. Process-based terrestrial modelling and forest statistics are successfully combined to improve model-based estimates of vegetation carbon stocks and their change over time. Application of the advanced model for 77 European provinces shows that model-based estimates of biomass development with stand age compare favourably with forest inventory-based estimates for different tree species. Driven by historic changes in climate, atmospheric CO₂ concentration, forest area and wood demand between 1948 and 2000, the model predicts European-scale, present-day age structure of forests, ratio of biomass removals to increment, and vegetation carbon sequestration rates that are consistent with inventory-based estimates. Alternative scenarios of climate and land-use change in the 21^st century suggest carbon sequestration in the European terrestrial biosphere during the coming decades will likely be on magnitudes relevant to climate mitigation strategies. However, the uptake rates are small in comparison to the European emissions from fossil fuel combustion, and will likely decline towards the end of the century. Uncertainty in climate change projections is a key driver for uncertainty in simulated land-atmosphere carbon fluxes and needs to be accounted for in mitigation studies of the terrestrial biosphere.</p> / <p>Kohlenstoffspeicherung in terrestrischen Ökosystemen reduziert derzeit die Wirkung anthropogener CO₂-Emissionen auf das Klimasystem, indem sie die Wachstumsrate der atmosphärischer CO₂-Konzentration verlangsamt. Die heutige terrestrische Kohlenstoffbilanz wird wesentlich von Klima- und Landnutzungsänderungen beeinflusst. Diese Einflussfaktoren werden sich auch in den kommenden Dekaden auf die terrestrische Biosphäre auswirken, und dabei möglicherweise zu einer positiven Rückkopplung zwischen Biosphäre und Klimasystem aufgrund von starken Bodenkohlenstoffverlusten in einem wärmeren Klima führen.

Die Ergebnisse dieser Arbeit zeigen, dass der Nettokohlenstoffaustausch zwischen terrestrischer Biosphäre und Atmosphäre unter heutigen klimatischen Bedingungen relativ sicher abgeschätzt werden kann, obwohl erhebliche Unsicherheit über die modelbasierte terrestrische Nettoprimärproduktion existiert. Prozessbasierte Modellierung und Waldbestandsstatistiken wurden erfolgreich kombiniert, um verbesserte Abschätzungen von regionalen Kohlenstoffvorräten und ihrer Änderung mit der Zeit zu ermöglichen. Die Anwendung des angepassten Modells in 77 europäischen Regionen zeigt, dass modellbasierte Abschätzungen des Biomasseaufwuchses in Wäldern weitgehend mit inventarbasierten Abschätzungen für verschiede Baumarten übereinstimmen. Unter Berücksichtigung von historischen Änderungen in Klima, atmosphärischem CO₂-Gehalt, Waldfläche und Holzernte (1948-2000) reproduziert das Model auf europäischer Ebene die heutigen, auf Bestandsstatistiken beruhenden, Abschätzungen von Waldaltersstruktur, das Verhältnis von Zuwachs und Entnahme von Biomasse, sowie die Speicherungsraten im Kohlenstoffspeicher der Vegetation. Alternative Szenarien von zukünftigen Landnutzungs- und Klimaänderungen legen nahe, dass die Kohlenstoffaufnahme der europäischen terrestrischen Biosphäre von relevanter Größenordnung für Klimaschutzstrategien sind. Die Speicherungsraten sind jedoch klein im Vergleich zu den absoluten europäischen CO₂-Emissionen, und nehmen zudem sehr wahrscheinlich gegen Ende des 21. Jahrhunderts ab. Unsicherheiten in Klimaprojektionen sind eine Hauptursache für die Unsicherheiten in den modellbasierten Abschätzungen des zukünftigen Nettokohlenstoffaustausches und müssen daher in Klimaschutzanalysen der terrestrischen Biosphäre berücksichtigt werden.</p>

Exploring age structure in Mediterranean cultures illuminates the social dynamics of intergenerational relationships that became more visible in late first and early second century early Christian texts, and especially in 1 Timothy 5.

Cette recherche se propose d’étudier l’impact du vieillissement futur de la population algérienne sur l’équilibre financier du système des retraites et les dépenses de santé. Après une période de croissance rapide de la population, l’Algérie est entrée dans une phase de vieillissement démographique. Cette dernière a marqué la pyramide des âges pour la premièrefois en 1998, avec une modification importante de la structure par âge confirmée par le dernier recensement de 2008. En Algérie, comme l’a été la baisse de la fécondité, le vieillissement de la population, dans les deux à trois décennies à venir, devrait suivre un rythme rapide, voire extrêmement rapide, comparé à celui observé dans les pays développés. Ce phénomène aura des conséquences dans beaucoup de domaines ; notamment au niveau du financement des retraites, et de la maîtrise des dépenses de santé. Dans les deux à trois décennies à venir les dépenses de retraites et de santé devraient connaître une croissance importante sous l’effet du vieillissement. Il incombe aux pouvoirs publics de s’y préparer et de s’y adapter afin de relever le défi qu’imposera le vieillissement futur de la population algérienne afin de garantir l’équilibre financier et la pérennité des deux systèmes, à savoir celui des retraites et de la santé. / The research aims to study the impact of future aging of the Algerian population on the financial balance of the pension system and health expenditure. After a period of rapid demographic growth, Algeria entered a phase of population aging. This was noticed on the age-sex pyramid for the first time in 1998, with a significant change in the age structure. Thischange was confirmed by the last census in 2008. In Algeria, as for fertility, aging is likely to follow a rapid or extremely rapid pace, within two to three decades, compared with observed experiences in developed countries. This will imply consequences in many areas including in pensions’ funding and health expenditure control. Within two to three decades, the pension and health spending will grow significantly as a result of aging. The government has to face the challenge of the future burden of aging of the Algerian population and to ensure the financial stability and sustainability of both systems, namely pensions and health.

The aim was selected in a commercial breeding (AGRO Vodňany a.s.) to analyze and evaluate herd reproductive performance of sows used for the production of piglets (final hybrids). The analysis was focused on the age structure of the sow, when the first and second litter was 28.8% on the 3rd to 5th litter 23.5% and the sixth and other litters of sows 47.7%.The annual renewal of the herd was culled 22.9% and 25.5% included sows for breeding.This breeding is used natural reproduction, where for the purposes of reproduction bred four boars lines of 48 (White paternity x Pietrain).The average gestation length breeding was 115.2 of days. In 2016, it was born an average of 13.8 piglet per litter, of which 11.5 piglet of live and been preserved was 10.2 piglet per litter.The length of the farrowing interval was 171,1 days and the onset of estrus after weaning piglets was an average of 4.9 days.Weaning is in monitored husbandry carried out between 28 to 31 day age of piglets.Part of this work was to evaluate zoohygiene also at stud and compared with the results of performance farms in the Czech Republic and recommendations for improving the results of husbandry evaluated. When comparing the results of selected indicators identified in Agro Vodňany a.s. with selected data published by the Czech Statistical Office for the South Bohemian Region and the Czech Republic in 2016, it was found that the number of piglets born per sow in the Czech Republic was 30.1 piglets. Piglets was born25.1 in South Bohemia and 24.3piglets was born per sow in Vodňany. The death of piglets from the number of births in the Czech Republic was 10.6% in the South Region accounted for 15.6% and in Vodňany it was 11.9%.The number of surviving piglets per sow in the Czech Republic was 26.9 piglets in South Bohemia have been preserved 21.3 piglet per sow and Vodnany during the reporting period have been preserved 21.4 piglets per sow.
